State Grid Zhongwei reinforces summer grid safety defenses

Rising temperatures, frequent thunderstorms, and seasonal gales have put the power grid under significant strain in Zhongwei, Ningxia Hui autonomous region.

In response, State Grid Zhongwei Power Supply Company has rolled out a tailored inspection plan for each major line and conducted comprehensive hazard sweeps to ensure reliable electricity supply.

For critical line sections, maintenance crews use infrared thermometers to check connectors, strain clamps, and other heat‑prone components. Any equipment defect is identified, diagnosed, and corrected early, preventing heat‑related failures.

To counter summer winds, the company combines drone overflights with ground patrols to manage transmission corridors. Teams clear lightweight debris such as tinfoil and plastic mulch, while laser devices remove foreign objects tangled in overhead lines.

Additional warning signs have been posted near farmland, while field personnel monitor protected areas to prevent oversized agricultural and unauthorized activity from entering protected zones. Safety campaigns encourage farmers to clear waste voluntarily and operate equipment properly, reducing external damage risks.

Patrols also carefully inspect tower footings along riverbanks, low‑lying areas, and slopes, guarding against tilting or collapse from rain‑induced erosion.

Leveraging visual monitoring technology, the company has detected and resolved over 1,000 corridor‑hazard cases through onsite and remote surveillance. It has also reinforced 458 prefabricated metal sheds and structures, nipping potential threats in the bud and strengthening readiness for peak summer demand.

Looking ahead, the company will build on these rectification efforts. Facing the dual strain of high loads and flood risks, it plans to strengthen targeted patrols on heavily burdened lines, permanent construction zones, and geologically fragile sites.

It will further refine its integrated online‑offline prevention system to guarantee stable, safe power delivery throughout the summer.
